+I. Man's highest glory may become the chief instrument of his trouble.+ The human tongue, or rather the power of speech, is a gift that stands preeminent among the good gifts of God to His creatures. It is man's most potent instrument of good or evil. The tongue of the statesman, when used wisely, may bring blessings on millions, but when it is made the tool of ambition it may entail misery upon generations. The tongue of a Christian, when used wisely, may be the means of bringing others into the way of life, but his unguarded words may be a stumbling-block in the way of many. The warning of the text reminds us that when the tongue is not kept in check by reason and consideration the glory becomes the means of ensnaring the whole man. The horse is a most useful servant to man, but the creature must be under proper control or he may be the means of inflicting the most serious injury upon his rider. If the rudder of a vessel is left to the guidance of the waves, the vessel is very likely to find herself upon the rocks. So with the tongue of man, it must be under the control of reason or it may bring its owner into danger and disgrace. When a man binds himself by solemn promises to a stranger of whose character he must be ignorant, he is very likely to involve himself and those dependent on him in much trouble, and perhaps in dishonour. A promise hastily made without due consideration of the consequences has often entailed upon a man years of suffering. +II. The same instrument which, thoughtlessly used, brings a man into a snare, may, when rightly guided, be the means of his deliverance.+ The promise made by Herod to Herodias (Matt. xiv. 7) was one which ought never to have been made. The king was ensnared by allowing his tongue to utter rash words, of which even _he_ upon reflection repented. In his case, without doubt, it would have been a much less sin to have broken his promise than to keep it. But in the case before us, the advice given by Solomon to his pupil is, not to break his word, but to use the same instrument by which he bound himself, to obtain, if possible, a release. This he is to do--1. _By means purely moral._ There are other means which a man might try. He might use threatening; he might employ falsehood; but these would be sinful. The only lawful means are those here implied, viz., words of persuasion and entreaty. 2. _Without delay._ He must endeavour to rectify his error at once; every day that passes over his head may be bringing nearer the day when he may be called upon to redeem his promise, and so he is to give "no sleep to his eyes nor slumber to his eyelids."
